Some people need to be erased for everyone's sake. Sometimes it's not wrong. A father like that can ruin multiple people's lives. That alone is a great crime.

You asked why people like Rem. I just stated my opinion. Emilia is boring, Rem felt like a true heroine which unfortunately was scraped. For me Re:Zero is already boring as it is. Removing the most interesting and cute character, and replacing it with a shallow one just made the series...
@Glomoro
Because Rem had character development. We saw her character growth, her growing attachment to the mc. Her suffering. Her devotion.
And for Emilia... She's the same as in s1e01. The heroine in distress, nothing much changed. She's kind of empty shell, pretty, cutesy, but nothing much...
A messy story. Feels like the most important is the edgy idea rather than story-telling. Feels like the author cared more for the shock value rather than tell a good story. Not much value here.
